Scale & Motion - RC Crawlers, Micro Upgrades, Model Kits & Scale RC Guides

The 1/18 scale mini crawler segment has grown considerably over the past few years, but it remains dominated by fleetside pickup designs and SUV-style bodies. The FairRC FCX18S K10 S Stepside Mod steps away from that pattern entirely. Built on the proven FCX18S chassis and then significantly reworked by FairRC's in-house FRC Mods programme, it arrives as a purpose-configured square-body Chevrolet K10 with a stepside rear bed — a body style that is genuinely uncommon at this scale, and essentially absent from the RTR market. This is not simply a repaint.

What is the FMS FCX18S GMC Sierra S? The FMS FCX18S Sierra S is a 1/18 scale crawler built on an officially licensed GMC Sierra S body — licensed directly by General Motors LLC. It ships RTR (Ready-to-Run) with a brushless motor installed from the factory, which remains a meaningful differentiator in the sub-$250 mini crawler segment where brushed power has been the norm. The FCX18 platform already underpins the K10 and LC80 variants . The Sierra S is the latest body on that chassis and brings the most aggressive off-road proportions of the three — 55° approach angle, 35° departure angle, and portal axles front and rear. On paper and in the hand, this is built to crawl, not just look good on a shelf.
